Wonderful. That is to say, I create a module that is not for sale, that people demand and you, far from offering support, are annoyed because another developer executed the idea and therefore you will not earn money. And that is why it invites you not to buy the module to buy it from you later. Agree.
But then you make modules that were created before. As for example, the direct messages module for instagram. Or it incorporates features that were already made separately as IGTV. But the one who gets upset is you. Sure.
And on top you threaten to ban. Are you sure that's the way?
